What is the normal range of plasma pH in neonates?

The normal range of plasma pH in neonates is established to be 7.35 to 7.45. This range signifies proper acid-base balance in the body, which is crucial for metabolic processes and overall physiological functioning. Maintaining this pH range indicates that the neonate's respiratory and metabolic systems are functioning effectively, allowing for efficient oxygen transport and carbon dioxide removal.

In neonates, pH levels can fluctuate more than in older children or adults due to various factors such as immature organ systems and adaptation to extrauterine life. However, the normal range of 7.35 to 7.45 is critical for ensuring that the neonate does not develop acidosis or alkalosis, which could lead to significant health issues. Thus, recognizing this range helps healthcare professionals monitor and manage the respiratory and metabolic status of neonatal patients effectively.
